I played for about 3 hours and it seems like combination of Dark Souls, Tomb Raider and a good story based game. Overall nothing new so far but packaged very well by picking good elements of other games. Think of how Horizon Zero Dawn was packed well.
Combat - Dark Souls
The combat system is Dark Souls. You have the standard attacks, parry, dodge, roll and block blaster fire with lightsaber etc. The combat and movements are very responsive. And it makes you feel like a proper Jedi when you block with blaster fire with lightsaber! They add force power to the mix as well but I have only tried 2 of them so far as you unlock them as you level up.
Unlike Dark Souls you have 4 difficulty levels and I was playing at the 3rd highest difficulty and I thought it was still not hard as DS but I have not fought any bosses yet. So far I have fought what seems like basic mobs and elite mobs (they get big HP bar showing up at the top of screen). The elites did proved to a challenge but none of them actually killed me yet.
If you die you will loose the exp but if you go back and hit the monster, you get your xp back. You also have bonfires around the map at which you can rest heal up and spend your skill point but mobs in the area will respawn. You also get DS style Estus Flask which you can use to heal yourself.
Overall very pleased with combat.
Exploration - Dark Souls/Tomb Raider/Zelda
I am only at the first plant after starting tutorial. But it looks very nice and its maze. There are lot of caves, tunnels and multiple levels so they have used vertically very well. Its also like mini island and connect in multiple ways. You can unlock shortcuts as well. There are also puzzle which are very simple so far but you need to use force power to solve them. Exploration is rewards with hidden chest all over the place. I can see couple of chest but I still not have figured out how to get to etc.
Here is also the annoying bit. You can climb but only at places where the game think you should. These places are not very obvious but I am beginning to spot them. If they want to jump and climb, I think they should have gone the whole way and did something like Assassin Creed.
Loot
You can customise your lightsaber and you also get armour drops. You also get droid side companion and it seems you can customises that as well. However not done much of it yet and I am also not sure if there are any stats or just cosmetic.
Story - ???
I have not seen much of the story so far but it does of feel SW for now. You are playing a set character and so far he seems fine and not whine little brat! It looks like they want to tell his backstory via flashback.
Performance
Playing at max setting at 3440×1440 with 1080ti and i5 4670k. Low FPS is around 40s, average around 50/60 and high around 75. This game doesn't always max out the CPU nor the GPU but GPU is mostly around 95%+. I still need to tinker with the setting but it can only get better so very impressed with how well its running at all max.
There seems to some micro stutter when the game moves between in engine rendered cut scenes and game world.
I wasn't actually planing to play this game at all so not looked into it much so was going in pretty blind. The reason why I started to play was that it seems like bargain at £15 for the month!
